Fudan Micro JFM7 vs AMD/Xilinx 7-Series: Can China FPGA Truly Replace Them?

One of the most frequent questions Duyuan Electronics receives over the past two years is: "We used to use Xilinx XC7K325T, and now we need a China-based replacement. Can the Fudan Micro JFM7K325T be dropped in directly? How much code do we need to change? Do we need to redesign the PCB? How much performance do we lose?" This article puts three mainstream model pairs from the Fudan Micro JFM7 series and the AMD/Xilinx 7-series side by side, and explains exactly to what extent a "drop-in replacement" really holds.

Building High-Speed Data Acquisition Cards with FPGA: Why FMC HPC + PCIe x8 Is the Golden Combination

Oscilloscopes, digitizers, phased-array radars, software-defined radios and high-speed vibration monitoring — the core of all these systems is "high-speed ADC sampling → data packing → transfer to the host for processing." Why must this step use an FPGA rather than an MCU, a DSP or a CPU sampling directly? Why have the FMC HPC connector and the PCIe x8 interface become the golden combination for high-speed acquisition cards? This article starts from a real 250MSPS acquisition project.
